WM. BURNS, OF ROME, OHIO.

MEAT-CUTTER.

Specification of Letters Patent No. 8,936, dated May 11, 1852.

of Ohio, have invented a new and useful Improvement in the Machine forMincing Sausage-Meat; and I do hereby declare the following to be a fulland clear description thereof, reference being had to the annexeddrawings, forming part of this specification, in which Figure l, is aview in perspective, of the box, and the propelling gearing. Fig. 2, isa vertical section, showing transverse sections of the cylinders andconcaves. Fig. 3 is an interior elevation of the double concavesfurnished with knives. Fig. 4, is an interior elevation of the doubleconcaves furnished with pins. Fig. 5, is a view of the upper cylinder,and Fig. 6, is a view of the lower cylinder.

The same letters occurring on the several figures, denote correspondingparts.

The nature of my invention and improvement consists, in arranging inseparate concaves, maintaining vertical positions, armed with pins onone side, and knives on the other side, two cylinders, the one, abovethe other, armed with knives, and pins, and so operating that the uppercylinder will receive the meat and partially mince it between the knivesof the concave, and allow it to descend to the lower cylinder, by whichit is minced to the required fineness, and discharged ;and myimprovement furthermore consists in, so disposing the knives, and pins,on the cylinders, and in the concaves, that the pins on the cylindersshall serve to clear the knives in the concaves, while the pins in theopposite concaves serve to prevent the ascent of the minced meat withthe rotation of said cylinders, and act as cleavers to the latter.

The box or case consists of a top board A,

provided with a feed opening (a) and a bottom board F, provided with adischarge channel I, through which the minced meat passes,and two sideboards B, G, grooved to receive the edges of two other boards D, E. Thetop and bottom boards are also grooved to receive the boards B, C, D, E,whereby the case is heldt-ogether.

The upper cylinder G, is mounted in bearings in the boards B, C, andhaving on one of its axles a cog wheel H, matching with a long pinion J.This cylinder is furnished with three rows of cutters e e e five in eachrow, arranged in straight lines at equal distances apart, and a row ofpins 9 of the same number.

M is the lower cylinder mounted in bearings in the boards B, C, andhaving on one of its axles a pinion L, also matching with the longpinion J, whereby the motion of the lower cylinder, is caused to beabout three times greater than that of the upper cylinder, by reason ofthe increased size of the cog wheel H. This lower cylinder, is in likemanner to cylinder G, armed with knives 11 z' a six in each row, and onerow of pins n of like number, arranged so as to pass between the knives,and pins, of the upper cylinder.

To the boards D, E, (and nearly embracing theupper cylinder) are fixedconcaves D E which are concentric with said cylinder, one of which E atthe upper and lower portion thereof, is provided with a row of radialknives 0 0 six in number, and the opposite concave D at the lowerportion thereof, has a row of pins on of like number; these cutters, andpins, are so disposed as not to interfere with those on the cylinder.The concaves E D unite with the concaves of the upper cylinder, and arein like man ner furnished with knives 0 c and pins 0% but of a numberone less than the upper concave, and are so arranged as not to interferewith t-heknives, and pins, on the lower cylinder. The meat is minced bythe knives on the cylinders, and in the concaves, and the pins, on eachcylinder is designed to keep the knives of the concaves free or clear ofthe minced meat, while the pins m n in the lower part of the concaves DD serve to clear the knives on the cylinders, and prevent the mincedmeat being carried upward by the rotation of the cylinders.

The discharge channel I, inclines downward from the lower part of theconcave E to allow the free egress of the minced meat, which is effectedby the rotation of the knives and pins on the lower cylinder. The

board D, has an opening in it'corresponding with the discharge channelI. J, is mounted in bearings in a frame K, and the rotation thereof iseffected by a crank handle P, on the axle of the upper cylinder,

The pinion v arrangement and construction of the several parts of mymachine, it will be seen that by putting the meat into the feed openinga when the cylinders are in motion, the knives and pins of the uppercylinder take hold of the meat and carry it immediately in contact withthe knives 0 a in the concave E where it is cut into pieces, anddelivered on I the lower cylinder which has a quick motion,

whereby the meat is carried around through the knives 0 0 in the lowerconcave, and

thence gradually discharged through the a feed opening a, and adischarging channel I, and the gearing for imparting to the cylinders arotary motion. I therefore do not claim as new any of these partsseparately considered, or irrespective of the manner, or arrangement, inwhich I propose in combination, to apply them, for the purposes, and toproduce the advantages specified, but

What I do claim as new, and desire to secure by Letters Patent, is-

Arranging in separate concaves, maintaining vertical positions, anduniting with each other, two cylinders, the one above the other, theupper one operating to partially mince the meat, and deliver it upon thelower cylinder, revolving at a greater speed, for reducing it to therequired fineness as described.

In testimony whereof I have hereunto signed my name before twosubscribing witnesses.
